Definitions
- the invention relates to a handle, in particular a door handle of a motor vehicle for a keyless access and / or driving authorization control system, with a housing made of plastic, in which an electronic unit is arranged, which detects an approach of a person and / or a touch of the handle and a encoded wake-up signal, which is transmitted capacitively to the person and forwarded to an ID transmitter.
- WO 2005/006261 A1 describes an electronic access control device for a secured interior of a motor vehicle, which has an ID transmitter with a transmitting and receiving device, a door with a door lock to be opened for the access of a person and an interior space, has a control unit connected to a transmitting and receiving device, which starts in the case of an intended door opening communication with the ID transmitter and receives a wake-up signal sent from the ID transmitter identification data signals.
- a lock unlocking of the door lock is performed by the control unit when the transmitted identification data signals of the ID transmitter coincide with the identification data present in the control unit.
- the transmitting and receiving device receives the identification data signals capacitively or inductively, wherein at least one of the signals, namely the wake-up signal and / or the identification data signals are capacitively transferable. It has been found that interference can occur when detecting the approach of a person or when the door handle is touched, as well as when the wake-up signal is transmitted capacitively. Furthermore, said device has a plurality of components, in particular due to the inductive transmission of the data signals, thereby increasing the assembly effort and the necessary space.
- the invention has for its object to provide a handle for a keyless access and / or driving authorization control system and a method for this, which avoids the disadvantages mentioned, in particular a handle and a method is provided which ensure reliable operation.
- the term door handle is generally used for a handle for a movable member, wherein the movable member may be, for example, a glove box, a trunk door, a tank lid or a vehicle door.
- the electronic unit has at least one communication surface which can be switched by at least two operating states by means of a switching element within a housing, the communication surface being a capacitive proximity sensor in a first operating state and a transmitting element in a second operating state the wake-up signal is transmitted to the person via a capacitive coupling.
- the capacitive proximity sensor detects from a certain distance the person who is informed to the control unit. Subsequently, the control unit switches by means of the switching element, the electronic unit in the second operating state in which the communication surface instead of a capacitive proximity sensor acts as a capacitive transmitting element.
- the transmission of the coded wake-up signal by capacitive coupling takes place with the involvement of the person who wishes access to the protected area of the motor vehicle.
- an immediate contact or at least a very small distance between the person and the movable element designed as a door handle is required.
- the communication surface After the communication surface has detected the approach of the person in its first operating state, the communication surface is in its second operating state after its switching. If the person desiring access to the motor vehicle touches the door handle, the wake-up signal is transmitted from the communication surface via a capacitive coupling to the person and finally to the ID transmitter.
- the ID transmitter may be in a garment of the person or even in a suitcase or the like, which is worn by the person without disturbances of the alarm signal occur. It is particularly advantageous that only one component is necessary for the capacitive proximity sensor and the capacitive transmitting element, whereby the required space can be kept low. To ensure a good functioning, the switchable communication surface is exposed as possible to the facing outer surface of the door handle, which is touched during the capacitive transmission of the person. This means that in particular no electronic components between the outer surface of the door handle and the communication surface are located.
- the communication surface is operated as a capacitive proximity sensor with an electrical voltage that differs from the voltage that is necessary for the transmitting element in the second operating state.
- This intelligent circuit of the communication surface is carried out by the control unit arranged in the door handle, which electrically operates the communication surface depending on the operating state that reliable approach of a person or a touch of the door handle and a transmission of the wake-up signal can be effected without being adversely affected by disturbances in the signal transmission to become.
- a corresponding alternating electric field is applied to the communication surface, as a result of which capacitively an approach or contact can be detected and alarm signals can be transmitted.
- the switching element that switches the communication surface to the corresponding state may be, for example, a relay or IC.
- a check is advantageously carried out within the ID transmitter.
- the ID transmitter sends back to the wake-up signal via its transmitting devices, a response signal in the form of identification data signals as a coded message back to the motor vehicle, which are received in particular by vehicle-side receiving devices.
- Lock unlocking the door lock is done by a control unit, when the sent identification data of the electronic key match with fixed in the control unit identification data.
- the control unit may be a control unit arranged outside the door handle.
- the receiving devices for receiving the identification data signals of the ID transmitter are preferably positioned on the motor vehicle. It is also conceivable to integrate the receiving devices on the door handle.
- the communication surface is arranged within the door handle, wherein there is a distance between the outer surface of the door handle and the communication surface.
- the distance is less than 10 mm, more preferably less than 5 mm and most preferably less than 2 mm.
- the communication surface may be rectangular or square. Other geometric shapes are also conceivable.

- the area between the outer surface of the door handle and the communication surface is advantageously made insulating.
- the communication surface which is advantageously a metallic surface, arranged on the door of the motor vehicle facing side of the door handle.
- a communication surface operating as a capacitive transmission / proximity sensor electrode is sufficient.
- the electronics unit has a printed circuit board on which the communication surface is arranged.
- the communication surface is arranged integrated on the printed circuit board, which can be rigid or flexible, for example, designed as a film.
- the communication surface may be a copper surface.
- the communication surface is arranged as a separate component within the door handle.
- the housing has a cavity in which the electronics unit is encapsulated in a non-conductive material, whereby the door handle receives its required strength.
- the cavity is designed with an inner wall, on which the communication surface can rest.
- the communication surface is connected via a line and to the control unit and then potted with the non-conductive material.
- at least one spacer element may be arranged between the voltage applied to the inner wall communication surface and the circuit board. This ensures, inter alia, that during the casting process, the communication surface reliably remains on the inner wall of the cavity.
- the spacer elements are advantageously made of plastic, which are positively connected before the casting process or non-positively connected to the communication surface and the circuit board.
- the communication surface may be a metallic surface coated on the inner wall of the cavity, which is in electrical contact with the printed circuit board.
- a further communication surface is arranged on the side remote from the movable element of the door handle, which is provided for a locking operation of the movable element.
- the further communication surface can be used for locking the movable element.
- This further communication surface is also switchable in at least two operating states by the control unit, in which case - to avoid repetition - reference is made to the aforementioned embodiments, in particular to claim 1.
- Said communication surface which is connected in the first operating state as a capacitive proximity sensor, detects from a certain distance the person who wants to close the vehicle.
- the electronics unit is followed by a switching of the electronics unit from the first operating state to the second operating state, in which the communication surface acts as a capacitive sensor element, from which the wake-up signal is transmitted via the capacitive coupling to the person as well as to the ID transmitter.
- the person-worn ID transmitter is awakened by the capacitive signal and sends a response signal or an identification data signal in the direction of the motor vehicle. On the vehicle side, a check of the identification data takes place. If a positive identification of an identification of a locking of the vehicle doors is caused.
- the door handle may be disposed on the outer surface of the housing, a metallic aperture, with the inside of the housing arranged communication surface is capacitively coupled.
- the metallic bezel may be a chrome bezel that enhances the design of the door handle. Since the metallic diaphragm is capacitively coupled to the communication surface arranged within the housing, the metallic diaphragm acts simultaneously as a proximity sensor or as a transmitting element, depending on the switched operating state. In this case, there is the possibility of capacitively coupling the metallic diaphragm directly via a protective circuit or capacitively coupling it via a coupling electrode.
- the object is achieved by a method for a keyless access control to a motor vehicle with a door handle comprising a housing made of plastic, in which an electronic unit is arranged, which detects an approach of a person and / or a touch of the door handle and a encoded wake-up signal, which is transmitted capacitively to the person and forwarded to an ID transmitter.
- a arranged on the door handle communication surface is present, which is switchable from a disposed within the housing control unit via a switching element in at least two operating states, wherein in a first operating state, the communication surface operates as a capacitive proximity sensor, which capacitively detects an approach, which is communicated to the control unit , which then switches the communication surface in the second operating state, in which the wake-up signal is transmitted via a capacitive coupling to the person and the ID transmitter.
- the electronic unit can be adjusted so that the approaching person, especially the hand of the capacitive proximity sensor is preferably detected only at a distance of about 5 to 10 cm. Subsequently, a corresponding changeover of the communication surface to its second operating state.
- the communication surface is operated such that a transmission of the wake-up signal takes place only at a touch of the door handle.
- the operating as a transmitting element communication surface can be operated with a corresponding reduced transmission voltage, whereby a known from the prior art disadvantageous radio link extension is not possible.
- Advantageous embodiments of the method according to the invention are listed in the subclaims.
- the wake-up signal can be transmitted only once or also several times capacitively to the person and then to the ID transmitter. Since the movement speed of the person's hand can be very different, it may be useful to send the wake-up signal several times, for example 10 times.
- the electronic unit can be set such that the first capacitive data transmission of the wake-up signal can also "skip" immediately before the touch, which means that a capacitive transmission can already take place before a contact.
- the communication surface is expediently switched to the second operating state for a short time, preferably for less than 3 seconds, more preferably for less than 2 seconds and particularly preferably for less than 1 second. After the second operating state, the communication surface is advantageously switched back into the first operating state.
- the communication surface can be switched to a third operating state for the reception of a capacitive response signal, which is transmitted by the ID transmitter and is transmitted via the person touching the door handle on the communication surface of the door handle.
- the control unit is suitably activated by the approach of the person and the capacitive transmission synchronized with the timing of contact.
- a switchover of the communication surface can take place immediately, with the transmission of the wake-up signal being variably delayed.
- the proximity sensor can detect the touch sensor exactly and then immediately emit the wake-up signal. This avoids incomplete received wake-up signals and shortens the overall response time.
- the security against eavesdropping is also increased as the signal is always routed directly to the ID transmitter via the body.
- the proximity sensor can be self-balancing, which adjusts to environmental influences and thus has a constant behavior.
